XPERCON and X-Peripheral clock gating
As already mentioned, the XPERCON register must be programmed to enable the single
XBus modules separately. The XPERCON is a read/write ESFR register.
The new feature of Clock Gating has been implemented by means of this register: Once the
EINIT instruction has been executed, all the peripherals (except RAMs and XMISC) not
enabled in the XPERCON register are not be clocked. The clock gating can reduce power
consumption and improve EMI when the user does not use all X-Peripherals.
When the clock has been gated in the disabled peripherals, no Reset will be raised once the
EINIT instruction has been executed.
